Question

我是在Android Studio上编写测试的新手。通过使用UiAutomator编写仪器测试，我完成了一些自动测试。但是，当我需要获得设备IMEI和服务状态（需要权限READ_PHONE_STATE）时，即使在清单和代码中添加了权限，也总是不允许执行SecurityException。

检查Android文档，我知道权限READ_PHONE_STATE处于危险级别，因此我需要在运行时从用户那里获得权限。但是问题是我的测试代码不包含Activity。我在网上做了几天的研究，包括在Stack Overflow中找出可能的解决方案，但是没有运气。

我尝试过的包括：

1。使用@Rule

@Rule 
public GrantPermissionRule mRuntimePermissionRule = GrantPermissionRule.grant(android.Manifest.permission.READ_PHONE_STATE);

2。使用shell命令：

myDevice.executeShellCommand("pm grant com.mp.rss android.permission.READ_PHONE_STATE");

3。使用PermissionRequester（我可以看到在Logcat中授予的权限，但仍然收到SecurityException）

PermissionRequester pr = new PermissionRequester();
pr.addPermissions("android.permission.READ_PHONE_STATE");
pr.requestPermissions();

在logcat中：I / GrantPermissionCallable：权限：android.permission.READ_PHONE_STATE已被授予！

4。尝试提示询问权限，但失败，因为我的测试程序中没有活动。

 int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 100;
    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M && context.checkCallingOrSelfPermission(Manifest.permission.READ_PHONE_STATE)
        != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.READ_PHONE_STATE )){
                ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.READ_PHONE_STATE}, MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
    } 
   }

这是我的清单。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mp.rss">

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.RREAD_PRIVILEGED_PHONE_STATE"/>
<uses-permission android:name="android.permission.READ_PHONE_NUMBER"/>


<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme" />
</manifest>

这是我的代码

 public class rss {
      private static UiDevice myDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
      private static Context context = InstrumentationRegistry.getInstrumentation().getContext();
      public static void writeDeviceinfo( ) throws IOException, NullPointerException, UiObjectNotFoundException {
        PermissionRequester pr = new PermissionRequester();
        pr.addPermissions("android.permission.READ_PHONE_STATE");
        pr.requestPermissions();
        try {
            TelephonyManager tMgr = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            writeLog("[PrintInfo] Device service is  = " + tMgr.getServiceState());
        }catch (NullPointerException e) {
            writeLog("[PrintInfo] Device service is = ");
        }
    }
}

这是我尝试的以上4种方法的异常消息

`java.lang.SecurityException: com.mp.rss.test from uid 10181 not allowed to perform OP_READ_PHONE_STATE

如何向Android工具测试添加权限READ_PHONE_STATE？
